This market will resolve in favor of the player that finishes the 2026 MLB Postseason with the most RBI. In the event of a tie for the most RBI, this market will resolve in favor of the tied player with the higher slugging percentage across the 2026 MLB Postseason. If a tie still persists, each tied player's market will resolve to "No" and the "Other" market will resolve to "Yes". Only RBI in 2026 MLB Postseason games will count toward this market. The 2026 MLB Postseason comprises the Wild Card Series, the Division Series, the League Championship Series, and the World Series. Regular season games, exhibition games, and any tiebreaker or "Game 163" will not be considered part of the 2026 MLB Postseason. The "Other" market will resolve to "Yes" if the player who leads is not among the listed players. If the 2026 MLB Postseason is cancelled, or the World Series has not concluded by November 15, 2026, 11:59 PM ET, every named player's market will resolve to "No" and the "Other" market will resolve to "Yes". The resolution source for this market will be official information from MLB; however, a consensus of credible reporting may also be used.
